Nikon CFI Plan Fluor 10X Water Dipping Microscope Objective

The Nikon CFI Plan Fluor 10X Water Dipping Objective combines the superior optical quality of fluorite glass elements with the specialized design of a water dipping objective, making it an ideal choice for electrophysiology, neuroscience research, and live tissue imaging applications requiring wide-field observation. Unlike conventional water immersion objectives that require a coverglass, this dipping objective is designed for direct immersion into aqueous solutions, making it perfect for imaging brain slices, organotypic cultures, and other live tissue preparations in physiological buffers. The plan fluorite optical design provides enhanced chromatic correction compared to standard achromat objectives, ensuring accurate color reproduction and improved contrast—particularly valuable in multi-channel fluorescence imaging and calcium imaging experiments. The 10X magnification offers a wide field of view for specimen navigation, region selection, and contextual imaging before switching to higher magnifications, while the 3.5mm working distance provides ample clearance for micromanipulation equipment such as patch-clamp electrodes, microinjection needles, and stimulation probes. The water immersion design eliminates refractive index mismatches between the objective and specimen, ensuring optimal image quality when imaging deep into aqueous preparations. Compatible with Nikon's CFI60 infinity optical system, this objective integrates seamlessly with Eclipse FN1 and other upright research microscopes equipped for electrophysiology, making it an essential tool for laboratories conducting patch-clamp recordings, multiphoton imaging, optogenetics, and other neuroscience techniques requiring wide-field visualization with superior optical quality.
